Hybrid tea rose plant named &#39;JACeleco&#39;

ABSTRACT

Hybrid tea rose plant having flowers with large flower size; compact, well-branched plant with glossy, dark green foliage; resistant to rust and powdery mildew and ability to own root from softwood cuttings.

GENUS AND SPECIES

Rosa hybrida

VARIETY DENOMINATION

‘JACeleco’

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a hybrid tea rose plant named ‘JACeleco’ which was originated by me by crossing the variety ‘Twobe’ seed parent, (PP 7901), with the variety ‘JACmag’ pollen parent (PP 3998).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new hybrid tea rose variety having the compact well-branched habit of the female (seed) parent combined with the large flower size of the male (pollen) parent.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

-   -   1. Large flower size.     -   2. Compact, well-branched plant.     -   3. Glossy, dark green foliage.     -   4. Resistance to powdery mildew and rust.     -   5. Ability to own root from softwood cuttings.

Asexual reproduction of this new variety by cuttings, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

COMPARISON WITH PARENTS

‘Twobe’ differs in plant habit. ‘JACeleco’ is shorter and rounded in habit. ‘JACeleco’ also has larger flower. ‘JACmag’ differs in flower petal count. ‘JACeleco’ has 30 petals under normal growing conditions compared to 25 petals for ‘JACmag’

COMPARISON WITH SIMILAR VARIETY

The closest variety is believed to be ‘Twobe’ which is compared above.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart© 2001, except where ordinary dictionary significance of color is indicated.

FLOWER

Observations made from January 2006 to June 2007 from plants commencing at two to three years of age grown in a garden environment at Somis, Calif.

-   Blooming habit: Continuous. -   Bud:     -   -   Size.—About 45 mm long and 30 mm in diameter when the petals             start to unfurl.         -   Form.—The bud form is long, pointed ovoid.         -   Color.—When sepals first divide, bud color is Red Group 43B             with patches of Red Group 43C and Red Group 43D in areas not             as exposed to sun. When half blown, the upper sides of the             petals are Red Group 43B on the petal edges with Red Group             49B to Red Group 49C on the surfaces just exposed to the             sun, and the lower sides of the petals are Red Group 43B on             the edges and Red Group 49C over the rest of the petal.         -   Sepals.—Color: Upper surface: Green Group 138B that in             bright sun can be overlain with Greyed-Purple Group 184B.
